JOHN H. OLY, OF NEW PORTAGE, OHIO.

WINDOW-SHADE TRIMMER.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed April 10, 1908. Serial No. 426,332.

To all whom it may concern:

Be it known that I, JOHN H. CLY, a citizen of the United States of America, residing at New Portage, in the county of Summit and State of Ohio, have invented new and useful Improvements in Window Shade Trimmers, of which the following is a speci fication.

This invention relates to window shade trimmers, and the object of the invention is to provide a simple, cheap and effective device of this character, one wherein the curtain is adapted to be positioned upon a roller and having adjustable members and an adjustable knife adapted to be moved to the proper position at which the curtain is to be cut, and the curtain unwound from the roll and in the process of unwinding brought into contact with the knife so as to cut the our tain a desired width.

lVith these objects in view the invention resides in the novel construction of elements and their arrangement in operative combination, hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a front elevation of a device constructed in accordance with my invention. Fig. 2 is a rear elevation of the same. Fig. Sis a transverse sectional view, illustrating a curtain mounted upon a roller and the method of cutting or trimming the curtain. Fig. 4 is a perspective view of the slidable knife member.

This invention comprises two primary members, constituting a stationary member 1 and a slidable member 2. Both the members 1 and 2 are provided with suitable curtain receiving brackets 3 of the ordinary construction. The member 1 is provided with suitable orifices adapted for the reception of retaining elements by which the member is secured upon a wall or other suitable location. The member 1 is provided with a longitudinal slot 1, extending a suitable distance and having its walls beveled or inclined away from the front face and towards its rear face as clearly illustrated in Fig. 2 of the drawings. The lower face of the member 1 as provided by the slot 4 is graduated as designated by the numeral 6. These graduations 6 are arranged in inches and parts of inches and are adapted to serve as a guidance for a sliding knife 7 provided upon the lower portion of the member 1. The member 1 has its front and rear faces provided with longitudinally extending channels 8, adapted for the reception of offsets 9 provided upon a U-shaped knife carriage 10. The knife 7 provides a downwardly extending inclined blade, having an offset body portion provided with perforations adapted for the reception of retaining elements by which the knife is positioned upon one of the sides of the carriage 10.

The sliding member 2 has a longitudinally extending tongue portion 11, having its sides beveled to correspond with the beveled portions provided by the slot 4 of the member 1. The tongue 11 is adapted to slide within the beveled cut away portion of the member 1.

The operation of the device is as follows: The curtain to be out is wound upon the ordinary spring roller and positioned upon the device between the brackets 3 of the mem-.

here 1 and 2. The member 2 is drawn a sufficient distance away from the member 1 to accommodate the curtain and roller, and the knife? is slid with its carriage along the member 1 until it is positioned adjacent the graduations determining the amount to be cut from the curtain. It is to be understood that the curtain is wound upon the roller when positioned in the brackets, and the curtain is now unwound causing it to contact with the knife 7 This process it will be seen cuts the curtain at the proper line. WVhen the curtain is drawn against the knife to its full extent, the curtain and roller are removed from the brackets of the members 1 and 2 and the wooden roller cut with a saw or other suitable device at the proper length. It will be noted that the upper portion of the blade 7 is rearwardly curved or inclined. This curved portion is adapted to answer the two-fold purpose of preventing the curtain getting behind the blade when being cut and to act as an indicating point by which the sliding knife may be accurately positioned adjacent the desired graduation upon the scale 6.

Having thus fully described the invention what is claimed as new is:

1. In a window shade trimmer, the combination of a fixed slidable member, a shade receiving bracket upon the fixed member, said fixed member being provided with an inwardly beveled longitudinally extending slot, indicating marks upon the fixed memher, and a slidable knife carriage provided with an inclined knife having a portion adapted to register with the indications also mounted upon the stationary member, and the slidable member having a head upon which is mounted a curtain bracket and being provided with a longitudinally extending beveled tongue adapted to engage within the beveled slot of the stationary member.

2. In a window shade trimmer of the character described, a stationary and a slidable member upon the fixed member, the fixed member having its sides provided with the longitudinally extending grooves, a knife carriage comprising a rectangular member having an open top provided with inturning flanges engaging the longitudinal grooves of the fixed member, and a cutting element or 15 knife upon the carriage.

In testimony whereof I, afiix my signature in presence of two witnesses.
